fossyPie Posted August 2, 2022 Share Posted August 2, 2022 Hi everyone, I've already spent a week researching, tried multiple configurations, boot settings, kexts and flags with no success, I'm using opencore on legacy boot mode, created usb on windows using diskpart by following the dortania guide. It just gets stuck at black screen little after verbose mode at start. Can anybody guide me or suggest a guide? Thanks in advance 🙂 Here is my potato : Intel 2 Duo E6750 (Conroe) Nvidia GT230 (Tesla) 6GB DDR2 Hitachi HDD 340GB Foxconn P45AL (Intel P45 chipset + ICH10) Wifi/Bluetooth N/A Realtek ALC888C audio Realtek RTL8111B ethernet Quote Link to comment https://www.insanelymac.com/forum/topic/352837-cannot-install-107-lion-using-opencore-black-screen/ Share on other sites More sharing options...

Your system can run up to OS X El Capitan and that, too, would be much better. You won't be able to do anything with Lion. Just noticed an error on the debug file : SmbiosLookupHost failed to lookup SMBIOSv3 - Not Found, and some other errors, I attach the log file fyi But it did not halt there. Actually I noticed lots of blank lines on the debug output file which indicates some misconfigration with VGA. I previously tried to install 10.11 El Capitan which is fully capable with my hardware, but some folks suggested that VGA output does not work on 10.7+ opencore-2022-08-03-015115.txt Edited August 3, 2022 by fossyPie latest log file after some configs Quote Link to comment https://www.insanelymac.com/forum/topic/352837-cannot-install-107-lion-using-opencore-black-screen/#findComment-2790605 Share on other sites More sharing options...
Slice Posted August 3, 2022 Share Posted August 3, 2022 In my experience VGA output from Nvidia and AMD cards always working.

fossyPie Posted August 3, 2022 Author Share Posted August 3, 2022 4 hours ago, Hervé said: You can get VGA out of nVidia discrete cards all the way to most recent macOS version. Too many people say incorrect things about VGA. It's mostly unsupported out of Intel iGPUs but not all and certainly not beyond Snow Leopard (eg: VGA out of laptops with HD4400 graphics works OOB up to Monterey). Output port capabilities on nVidia cards is controlled by NVCAP value. If you do not get VGA output OOB, you usually have to find the correct value to set to NVCAP to obtain such output. Here's an example: https://www.insanelymac.com/forum/topic/336881-can-i-enable-vga-port-on-nvidia-gpu-witch-natively-supported-under-mojave/#comment-2654111 Glad to know that VGA can work on El Capitan 11.7 🙂 which is the latest one supports a Conroe CPU. It'd be great if you can provide a link to patch/fix for VGA. Btw should I use the latest OpenCore or older versions would work best for my setup? note: I do not have access to a real mac or a hackintosh Quote Link to comment https://www.insanelymac.com/forum/topic/352837-cannot-install-107-lion-using-opencore-black-screen/#findComment-2790650 Share on other sites More sharing options...

Thats cool .. Does VGA work OOP on that one and can you mention the clover version which works on your setup? I will try to research and install on my own first Quote Link to comment https://www.insanelymac.com/forum/topic/352837-cannot-install-107-lion-using-opencore-black-screen/#findComment-2790660 Share on other sites More sharing options...

Yes I think E5450 is all I need to get pass that SSE limit ... Cant wait to see Slice's reply on which clover version he used to install El Capitan on his Conroe computer ...

Avery B Posted August 3, 2022 Share Posted August 3, 2022 What are the device properties you currently have set? I made a calculator to figure out what the NVCAP value should be (https://github.com/1Revenger1/NVCAP-Calculator). I took a random GT 230 rom but a valid value would be "05000100 10000300 0c000000 0000000f 00000000", with each DVI port on it's own head. (Not sure TV does anything or is even supported, but it's mentioned here so I added it) 1 Quote Link to comment https://www.insanelymac.com/forum/topic/352837-cannot-install-107-lion-using-opencore-black-screen/#findComment-2790707 Share on other sites More sharing options...

Your system can run up to OS X El Capitan and that, too, would be much better. You won't be able to do anything with Lion. Looks fairly simple to add data to SsdtPrGen to generate the data for OpenCore, if OP is willing to put in the effort. Once downloaded, you can edit Data/UserDefined.cfg and add in the data for the processor. In the case of the E6750, an entry would probably look like: // Model, TDP, Min freq, base freq, turbo, cores, threads, type, BCLK E6750, 65, 2000, 2667, 2667, 2, 2, 0, 333 Had to spend a few minutes scouring the webs for all the numbers (I used FSB frequency instead for BCLK as well), but I think that should be about right? Probably would've been easier to figure out all the values if I had the processor in front of me and HWInfo or similar application 😅 Quote Link to comment https://www.insanelymac.com/forum/topic/352837-cannot-install-107-lion-using-opencore-black-screen/#findComment-2790725 Share on other sites More sharing options...

fossyPie Posted August 4, 2022 Author Share Posted August 4, 2022 (edited) I just have followed this guide so far could not boot Clover (black screen loop),... I think because my MB does not support UEFI boot... So can anyone suggest a similar guide for legacy boot? Or what should I do exceptionally to boot on legacy bios mode?

I just quickly tested it without touching anything and for the first time ever I managed to see the apple logo 😃 however, it just restarted the pc after some loading at around 50%... Now I need to figure out what changes should I make. btw does kexts and drivers depend on Clover/Opencore version?

Slice Posted August 5, 2022 Share Posted August 5, 2022 All kexts and drivers intended to use with Clover. Opencore may have a block for them. All versions are working in 10.11 up to BigSur. You may replace them with modern version but be sure they will work. I can propose you to make first a working system and only after that try to update kexts. Opencore guide is not the bible to trust without check. 1 Quote Link to comment https://www.insanelymac.com/forum/topic/352837-cannot-install-107-lion-using-opencore-black-screen/#findComment-2790783 Share on other sites More sharing options...
fossyPie Posted August 5, 2022 Author Share Posted August 5, 2022 I've managed to boot and start the re-install process, but it's asking for apple id for some reason, I did not see any option to skip it... so I tried my original apple id (which I was using on my iPhone previously)... but it throws an error "this item is temporally unavailable" and does not let me to begin installation. Made a quick search but could not find a working solution So Is the offline installation my only option? note: I already have -no_compat_check on the bootargs Quote Link to comment https://www.insanelymac.com/forum/topic/352837-cannot-install-107-lion-using-opencore-black-screen/#findComment-2790814 Share on other sites More sharing options...

Slice Posted August 5, 2022 Share Posted August 5, 2022 Do you have ethernet attached? Did you include a proper LAN driver into kexts folder? My EFI doesn't contain your LAN driver. I may propose Realtek LAN v3 from my signature.

Guest ricoc90 Posted August 5, 2022 Share Posted August 5, 2022 As far as I know the Recovery installer indeed does require you to log in. At least that used to be the case on genuine macs. Using a full installer should work fine. P.S. I indeed meant El Capitan.

It just will not let me to proceed with the installation, even if I use one of my old icloud accounts for the sign in. After doing some research it looks like there is no fix for that yet...
